' PHONOGRAPH.

Specification of Letters Patent.

Patented Mar. 8, 1910.

To all whom it may concern:

Be it known that I, FRANK- L. DYER, a citizen of the United States, and a resident of Montclair, in the county of Essex and State of New Jersey, have made a certain new and useful Invention in Phonographs, of which the following is a'description.

My invention relates to phonographs, and the object thereof is, broadly speaking, the production of a compact and efiicient device for the conveying and dissemination of sound in the reproduction thereof. More specifically, my device is an improvement on the invention of Peter Weber disclosed in his application for improvements in phonographs, Serial No. 509,061, filed on even date herewith. In the invention of the said Weber, a structure is provided wherein the cover for the phonograph is pivoted and when in open position may be supported in such position that a sound conveying tube connected with the neck of the reproducer may deliver the sound waves set up by the vibration of the reproducer diaphragm into the interior of the said cover. The cover is provided in its interior with sound deflecting means and means for conveying the sound so deflected smoothly to the open or bottom end of the cover, this sound conveying means within the body of the cover being of such a character as to amplify the sound. In my improvement on this structure, the sound conveying tube consists of telescoping sections supported within the cover, whereby, when the cover is in open position, the tube may be extended into the same to deliver the sound. waves from the reproducer against the deflecting means wlthin the cover, while, when the cover is in closed position incasing the honograph, the sound conveying tube or orn 1s collapsed within the same. By this construction, sound conveying and amplifying means of suflicient amplification'are provided in a com act s' ace when the cover is open, the whole device being self-contained andcompact when the cover isclosed'. 4

For a moreperfect understanding invention, attention is hereby directed to the accompanying drawing, this specification, representing an end. elevationof a phonograph equipped with my deyice the sound conveying tube and the cover ein shown in section for the open 7; positionv o the cover, these parts being forming part of shown in dotted lines in the positions occupied thereby when the cover is closed.

Referring to the drawing, the sound box 1 of the reproducer is carriedby the traveling arm 2 which slides -upon guide rod 3 mounted in bracket 4 which is supported upon bed plate 5 carried by the supporting cabinet 6, as is common. The neck 7 of the reproducer is connected by a. rubber or other elastic connection 8 to the sound conveying tube 9, the end of connection 8 fitting over a reduced diameter of the small end of the sound conveying tube 9 to form a flexible or telescoping connection thereby. The bracket- 10 is suitably secured preferably to the rear side of easing 6. Upon this bracket '10 the bracket 11 to which the cover 12 of the phonograph is rigidly secured as by screws 13,'is p1v0ted, as shown at 14.

The cover 12 is adapted to swing through a right angle about a pivot 14:, the cover being shown in its closed position in dotted lines, and in its open position by the full line structure. It is, of course, obvious that the open position of the cover need not be exactly 90 degrees away from the closed position. The outer end of bracket 10 carrying pivot rod 14 is provided with a nose 15 upon which a corresponding lug on bracket 11 rests when the cover is in open position, supporting means for the cover thus being provided when the cover is moved through approximately degrees from itsclosed position, or to whatever positionthe cover occupies when open. It is, of course, obvious that if desired, additional supporting means for the cover when in 0 en osition' may be provided. The inside o the top of the cover is provided with a sound deflecting surface 16 against which the sound waves conveyed by tube 9 are. adapted to be directed and smoothly deflected therefrom to the sound conveying and amplifying surface 17 within the cover by which the sound waves are directed to the open end of the cover. The surface 17 may be tapered as shown, or given any other desired conformation. Thetube 9 is preferably supported when the cover is in open so of, and means for conveying and directing,

earner tending diametrically across the inside of 7 sound from said reproducer to said amplifier the cover'from the upper to the lower portion of the surface 17 and passing through the upper and lower surfaces of the tube 9. The rod 18 is provided with a suitable supporting means for the tube 9, as the enlargemerit-19, which, as shown in the drawing, is provided on rod 18 immediately below the lower surface of the tube 9. By this means, the tube 9 rests upon the ball or enlargement 19 and may swing pivotally aboutrod 18. Tube 9 is provided with a plurality oftelescoping sections 20, the larger end of each of which fits snugly within the smaller end of the adjoining section. When the cover is in open position, these sections are drawn out to the greatest extent possible to form a continuous tube, the diameters of the respective ends of the various sections being so chosen as to prevent the complete withdrawal of one section from the next. When it is desired to close the cover, the elastic connection 8 is simply removed from its connection with the neck of the reproducer, when the cover may be closed, the various sections 20 of the tube 9 then collapsing into the position shown in dotted lines in the figure. Defiecting surface 16 on the inner side of the cover may be of any desired conformation for smoothly guiding the sound waves to the mouth of the cover without loss of the same. As shown in the drawing, this surface preferably consists of two smooth and similar curves extending from apex 21 op osite the axis of tube 9 and delivering sound waves therefrom to the surface 17.

Having now described my invention, what I claim and desire to protect by Letters Patent of the United States is as follows:

1. In a sound reproducing machine, the combination with a reproducer and a support therefor, of a cover for the reproducer, means pivotally supporting said cover from the side of said support, whereby said cover may be supported in open position with the vertical axis of the cover in a substantially horizontal plane, said cover being provided with a sound amplifier on the interior therecomprising a telescoping sound conveying tube connected to the neck of said reproducer and adapted to be extended into said cover when the latter is in open position, or collapsed within the same when the latter is in closed position, substantially as described.-

2. In a sound reproducing machine, the combination with areproducer and a support therefor, of a cover for the reproducer,

means pivotally supporting said cover and means whereby said cover maybe supported in open position, said cover being provided on the interior'thereof with means for deflecting and guiding sound waves impinging on the inner side of said cover to the open end thereof, and means for conveying and directing sounds from said reproducer into the interior of said cover and against said deflecting means, said conveying means C0111- prising a telescoping tube adapted to be extended into said cover when the latter is in open position and collapsed within the same when the latter is in closed position, substantially as described.

3. In a sound reproducing machine, the combination with a reproducer and a support therefor, of a cover for the reproducer, means pivotally supporting said cover and means whereby said cover may be supported in open position, said cover being provided on the interior thereof with means for deflecting and guiding sound waves impinging on the inner side of said cover to the open end thereof, means for conveying and (lirer'ting soundsfrom said reproducer into the interior of said cover and against said defleeting means, said conveying means C0111- prising a telescoping tube adapted to be extended into said cover when the latter is in open position and collapsed within the same when the latter is in closed position, and means within said cver for supporting said tube, substantially as described.

This specification signed and witnessed this 9th day of July 1909.
